13 Claims.

ing:

First, I have provided an arrangement which prevents the pen from being introduced into the ink beyond the pen point and at the same time I have provided a reservoir of sufiicient capacity to insure that the barrel of the pen may be completely filled with this limited insertion of thepen. 7

Second, I have provided a cap for the bottle by which the amount of ink or other liquid drawn into the auxiliary reservoir may be controlled by a rotary movement of the cap.

Third, I have arran ed for embodying the 3 invention in several forms and have provided an adapter by which the ordinary ink bottle may be converted into my improved type.

Other objects of the invention will become more apparent-as the description proceeds, par- 39 ticularly where reference is made to the accompanying drawings:

1930. Serial No. 477,695 (01. 120-459) Figure 12 shows a modified structure somewhat similar to that shown. inv Figure 10;

Figure 13 is another modified arrangement.

Referring to the construction as illustratedin Figure 1, 15 represents the bottle or container, having the reduced neck portion 16 which; in. this particular instance, has threads 17 formed in the surface of the container.- 18is the auxiliary reservoir mounted in the top of the bottle andhaving the cylindrical portion 19 and the enlarged mouth 20. The member 18 has atop' annular flange 21 for engaging the top of the bottle and a gasket 22 is provided to efiect a seal. For clamping the auxiliary reservoir to the con.- tainer there is a threaded'collar 23. having the inturned flange 24 engaging the top surface of the auxiliary reservoir. The seal is eiiected byv screwing the collar on the neck of the bottle until a tight joint is made. "The auxiliary reservoir communicates with the bottom of the bottle 15 through a conduit 25 which may be formed of rubber tubing or other suitable means. t

26 is a cap havinginternal threads 27. for engaging the external threads28ongthe collar 23; Projecting inwardly fromthe cap is a piston 29 mounted concentrically 10f the. cylindricalpore tion, 19 for engagement therewith. The "piston 29 is preferably secured to the cap by-a-pin 30 to permit the piston to slide intothe cylinder without rotation whilepthe cap is being rotated; With the construction. as, thus far described it will be observedthat rotation of the canon the threaded calla-r23 causes the piston to be drawn axially into the cylinder and the air trappedin the reservoir is thus forced out .throu'ghithe conduit 25 into the container. Therefore upon with drawal of the: piston; 29 by unthreadingthe cap, a predetermined amount of-liquid is drawn into the auxiliary reservoir where it is available'for use in filling the fountainpen- In order to insure the right quantity of liquid in the auxiliary reservoir a stop may be provided to determine the amount of rotation of the cap. As shown in Figure 6 this stop mayconsist of an abutment 31 formed on the threadedcole lar which is. adapted to; engage the. edge formed in the. side wall of the collar. 1

.In the operation of the device it-is essential that a tight seal be maintained between the top flangeZl and the top of the bottle and this sea] is determined by the pressure of the flange ion the gasket which in turn is determined by the rotation of the threaded collar 23. Forzcon venience in'rotating the collar 23 the cap: 26 may be threaded onto the collaruntil the edge 32 strikes the abutment 31 whereupon a further rotation of the cap will give an additional turning movement to the collar suflicient to insure a tight seal. It is also desirable to remove all of the parts from the container without having the user come in contact with the liquid in the container, and I have therefore provided an arrangement which permits all of the parts to be removed as a single unit. The cap 26 is provided with a pin 33 which is insertable through an aperture 34 into engagement with a corresponding aperture 35 in the collar 23. The pin is preferably mounted on a spring arm 36 so as to be normally out of engagement with the collar 23. When, however, it is desired to remove the parts as a unit the spring may be manually depressed until the pin engages the aperture 35, this looking all the parts together so that rotation of the cap also rotates the collar. The reservoir member 18 is removed with the cap and collar because of the'frictional engagement of the same with the piston 29 carried by the cap.

In the modified construction as shownin Figures '7, 8, and 9 the bottle or container 15 has a plain neck 41 of conventional type provided with a bead 42 at the upper end thereof. For converting such a bottle into a device embodying my invention I provide a split collar 43 made in two complementary portions which can be inserted around the neck of the bottle. The upper collar 44 is of a depth to flt beneath the head 42 and there is a flared skirt portion 45 for fitting the enlarged portion of the bottle. The collar' 44 has raised portions 46 forming threads which are adapted to receive the internal threads of the threaded collar 23 previously referred to in Figure 1. Thus by threading this collar member 23 onto the split collar, the flange 24 exerts a pressure on the auxiliary reservoir and clamps the same onto the neck of the bottle. The threaded cap is the same as in the preceding example.

Figure 10 shows another modification in'which the auxiliary'reservoir is provided with a guideway 50 for receiving the pen. The upper end of the guideway has the cylindrical insert 51, the diameter of which is small enough to prevent the lower end of the pen above the nib from enter ing the same. Thus assuming that the level of the ink does not get above the top of theguide 50, it will be apparent that the barrel of the pen will at all times remain unsoiled. It will be noted that the guideway. 50 is inserted within the enlarged reservoir52 so that the filling of the pen will not draw down the level of the ink below the filling aperture in the pen. Communication between the reservoir withinthe guide 50 and outside of the same-may be maintained in any suitable manner, as for example, by providing the aperture 54 in the guide 50 at a point near the bottom of the reservoir.

Figure 11 illustrates another modified form for preventing the soiling of the pen barrel. In this modification the auxiliary reservoir has an enlarged lower portion 55 and a smaller entrance end 56 formed by the taperingside walls; In

' both Figures 10 and 11 the construction is such asto prevent the insertion of the pen barrel into the ink while providing sufiicient capacity in the auxiliary: reservoir to fill the barrel without lowering the level below thefilling aperture.

In the modification shown in Figure 12 the auxiliary reservoir member 18 is provided with a cylinder 60 extending upwardly above the annular flange. The collar 23 has also the up wardly extending annular flange 61 rising above the inturned flange 24 and surrounding the cylinder 60. The annular flange has a threaded external contour 62 for cooperating with the threads on the cap 26 and there is also the inturned flange 63 adapted to extend within the annular recess 64 on the underside. of the cap.

The piston 29 is, in this instance, mounted in a sheet metal container 65 which in turn is secured to a metal pin 66. The pin has external threads 67 which cooperate with a threaded aperture 68 in the cap. The pin projects through the'cap and serves to receive a wing lock nut 69. Thetop of the pin is also provided with a coin slot 70 by means of which the pin may be adjusted in the cap to vary the position of the piston 29 in the cylinder 60. Thus by adjusting the pin the relation of the plunger to the cap may be adjusted as desired and consequently the displacement of the piston in the cylinder 60 may be varied so as to draw any desired amount of fluid into the reservoir 18. If desired the stem may be calibrated as indicated in Figure 12 to denote the amount of fluid which will be drawn to the reservoir corresponding with the various settings of the pin 66. These calibrations are designated in the drawings as 1 cc., 2 00., etc.

In Figure 13 the adjustment of the piston to obtain different volumetric displacements may be obtained by providing. a threaded collar 71 on the outer flange 72 of the cap 26. This collar 71 has the lower edge 73 arranged to seat upon the flange 24 of the collar 23 when the cap is threaded down to its lowest position. In this modification the piston 29 may be permanently secured 110 to the cap and the variation in displacement is obtained by adjusting the collar 71 on the outer flange '12. If desired this device may be calibrated by providing the graduations '75 on the outer circumference of the. collar as illustrated 115 in Figure 13.

In all of the modifications described above the piston is preferably made of a resilient material forming a seal with the corresponding cylinder but capable of being easily manipulated in and 120 out of the cylinder. Anysuitable material may be used but it is preferable to use rubber, cork or other yieldable materials.
